BICYCLE.

SPECIFICATION forming part of Letters Patent No. 592,169, dated October19, 1897.

Application filed October 29, 1896. Serial No. 610,424. (No model.)

To all whom it may concern:

Be it known that 1, JOHN CARLYLE RAY- MOND, of New York city, in thecounty and State of New York, have invented a new and I ImprovedBicycle, of which the following is a full, clear, and exact description.

The object of the invention is; to provide a new and improved bicyclewhich is'simple and durable in construction, and arranged to enable therider to conveniently steer the machine and drive it at a high rate ofspeed.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter-and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of the improvement. Fig. 2 is an end .viewof the same. Fig. 3 is a plan view of the combination handle-bar andhandle-crank. Fig. 4 is an enlarged sectional side elevation of thejointf'or the handle-bar sections, and Fig. 5 is a crosssection of thesame on the line 5 5 of Fig. 4.

The bicycle, as shown in Figs. 1 and 2, is provided with a drive-wheelA, the aXle or shaft B of which is journaledin suitable bearings in afork 0, provided with a rearward extension 0, carrying a guidewheel D.On the axle or shaft B are secured the pinions E in mesh withv internalgear-wheels F, journaled independently of one another, by having theirshafts E mounted to rotate in suitable brackets 0 extending from themembers of the fork 0.

On each of the shafts E is secured a crank G, carrying at its outer enda pedal H, andposite each other when the links I are used for connectingthe handlecrank .with' the cranks G, used for turning the internalgearwheels F.

Now it will beseen that by the arrangement described, the rider seatedon the seat L can use his feet on the pedals H, to turn the .cranks Gand internal gear-wheels F, so as to cause the latter to' rotate thepinions E, and consequently the shaft B and drive-wheel A. The rider canalso turn the handle-crank J in its bearing in the bracket K, so thatthe motion of the handle-crank is transmitted by the links I to thecranks G, to assist in turning the latter, todrive the wheel as abovementioned. Thus the rider can use both hands and feet for propelling themachine forward. The handle-crank J can also be used for steering themachine by manipulating the handle-crank accordingly, and turning thesteering-post in the steering-head O and carrying the fork O. 1

When the rider desires to use the pedals H only, and not thehandle-crank for assisting in the propulsion of the wheel, then thelinks I are disconnected from the cranks G and sections J and J 2 of thehandle-crank J. The sections J and J 2 are now placed in alinement witheach other, as indicated in Fig. 3, to be used only as an ordinaryhandle-bar.

In order to permit of conveniently changing the relative positions ofthe sections J J I provide'th'e inner end of the section J 2 with asquare recess J adapted to be engaged by a square offset J 4 on theinner end of the other section J. A set-screw J 5 serves to fasten theoffset J in placeon the section .1, as is plainly indicated in Fig. 4:.The handle-bar J can be fastened in place at its joint in the bracket Kby a set-screw K whenever the bar is to be used only as ahandle-bar; butwhen it is used as a handle-crank the set-screw K is unscrewed to permitof turning the bar in the bracket K. For changing the positions of thesections it is necessary to turn the bar so as to bring the; set-screw J5 into the opening for the set-screw K, to permit of removal byunscrewing the'set-screw J 5 and pulling the reduced end J 4 out of theopening J A half turn given to the section J brings its handle end inalinement with the handle end of the other section J and the parts areagain fastened together while in this position by screwing up theset-screw J 5 and then turning the bar J to the desired position, andthen using the set-screw K to fasten the handle bar in place in thebracket K.

It will be seen that by the arrangement described the rider canconveniently steer the machine and drive it at a very high rate of speedwithout overexerting himself. It will further be seen that the bar J canbe used as a rigid handle-bar on the steering-post, or as a combinationhandle-bar and handlecrank for assisting in the propulsion of the wheeland the steering of the same, as above explained.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination with the front fork, adrive-wheel mounted in the fork, and a pinion on each end of the shaftof the drivewheel, of internal gear-wheels mounted 011 the fork andmeshing with the said pinions, crank-arms on the gear-wheels andcarrying pedals on their outer ends, a combined handlebar andhandle-crank mounted in a socket carried by the steering-head, andformed of two crank-sections adjustably secured together, wherebythesections can be held diametrically opposite each other or in alinement,and links detachably secured to the crank of the internal gear-wheel andto the sections of the handle-bar, substantially as described.

2. A combined bicycle-handle and handlecrank, consisting of twocrank-sections, one provided with a iongitudinally-extending a11- gularsocket in its inner end and the other with a correspondingly-shapedinner end fitting in the socket, and a screw projecting into the socketand engaging the end of the section in the socket to lock it therein,substantially as described.

3. The combination with abracket adapted to be secured to thesteering-head of a bicycle and provided with a bearing, of ahandlebarmounted in the bearing and held therein by a set-screw, said handle-barbeing formed of two crank-sections each provided with a collar, onesection having a longitudinallyextending angular socket in its inner endand the other a correspondingly-shaped end fitting in the socket, and aset-screw projecting into the socket into engagement with the end of thesection in said socket, substantially as described.
